24 out of 28 eggs hatched fine...the last 4 didn't even pip. I left them in the bator and today I decided to open them (after I candled again to make sure there was no movement). In 3 of the eggs there were fully formed chicks,although they each had a mass attached to their bellies. Looked to be a sac of intestines and fluid. The 4th one looked to have stopped forming around the 14th day or so, mostly liquid in that egg.
